THE COGENERATION. WHAT IS IT? WITH TRIGENERATION The cogeneration is the combined production of electrical and thermal energy; the latter is made
Trigeneration system is a plant designed to produce cold water (>7°C) besides electricity and thermal
available as hot water, hot air or steam depending on the technology adopted according to the
energy, through the employment of a Lithium Bromide absorption chiller which use part of thermal
customer requirements. Moreover, the same technology may produce cold energy for refrigeration
energy produced by the Cogeneration plant. This configuration reduces the consumption of conventional
uses (tri-generation).
